1 utility list Denver County, Colorado, in the service territory they reported to EIA for 2024: Public Service Co of Colorado.
Its average residential price was 15.05¢ per kilowatthour, against a Colorado average of 14.92¢ and a US average of 16.48¢. Each price is the utility's figure for all of its Colorado customers, not for this county alone.
The median SAIDI they reported was 351.7 minutes per customer including major event days; the median among all Colorado utilities reporting was 157.8.
The Census Bureau estimates the county's population at 740,613. EIA does not publish customers by county, so which utility serves a given address has to be confirmed with the utility or the state utility commission.
Average price is revenue divided by sales for the sector and year; it is not a tariff rate. Reliability figures are as reported by utilities to EIA on Form 861 and may use different calculation methods. Figures are for each utility's whole Colorado operation; EIA publishes nothing at county level.
